A DNA cassette containing an Arabidopsis C repeat/dehydration-responsive element binding factor 1 (CBF1) cDNA and a nos terminator, driven by a cauliflower mosaic virus 35S promoter, was transformed into the tomato (Lycopersicon esculentum) genome. These transgenic tomato plants were more resistant to water deficit stress than the wild-type plants. The transgenic plants exhibited growth retarda...

The stress resistance of plants can be enhanced by regulating the expression of multiple downstream genes associated with stress resistance. We used the Agrobacterium method to transfer the tomato jasmonic ethylene responsive factors (JERFs) gene that encodes the ethylene response factor (ERF) like transcription factor to the genome of a hybrid poplar (Populus alba x Populus berolinensis). Eigh...

Canola (Brassica napus L.) is an important oilseed crop. A serious problem in cultivation of this crop andyield loss, are due to fungal disease stem rot caused by Sclerotinia sclerotiorum. The pathogenesis-related(PR) proteins have the potential for enhancing resistance against fungal pathogen. Thaumatin-like proteins(TLPs) have been shown to have antifungal activity on variou...

Rose is the most favorite cut flowers all over the world. Production of high-quality flowers, prevention, and delay of flower senescence, is a major goal in floriculture. Now a day, biotechnological approaches have been used to improve ornamental attributes. Tissue culture and genetic transformation appear to offer valuable advancements for operating floral characteristics. In this study, after...

Transgenic plants expressing a foreign gene are a suitable system for the production of relevant immunogens in high amounts that can be used for the development of a new generation of vaccines against a variety of infectious diseases. In the present study, the expression of the nucleocapsid (N) protein of hantavirus serotype Puumala in tobacco and potato plants was investigated. Transgenic toba...

The presence of marker genes encoding antibiotic or herbicide resistances in genetically modified plants poses a number of problems. Various techniques are under development for the removal of unwanted marker genes, while leaving required transgenes in place. The aim of this brief review is to describe the principal methods used for marker gene removal, concentrating on the most recent and prom...
